陈述句、一般疑问句、特殊疑问句.ppt

,专项练习一,陈述句、 一般疑问句、 特殊疑问句,必备知识点： be动词：am、is、 are、 was、 were；小学 阶段，be动词后只接名词，形容词或动词的ing形式。 助动词：do、does、did、 have、 had；助动词后的动词用原形。 情态动词can、must、will、may、need等；情态动词+动词原形,一、肯定句、否定句定义 1肯定句：表示肯定的意思, 即不含有否定 词“不”。 例：我是一个学生 I am a student. 他去上学 He goes to school. 2否定句：表示否定的意思。 例：我不是一个男孩。 I am not a boy 他不去上学 He does not go to school.,二、一般疑问句 （一）、什么是一般疑问句 用Yes或No作答的疑问句叫一般疑问句。一般疑问句还有下列特点： 1、以be动词、助动词或情态动词开头； 例：Is your father a teacher? Does Catherine like animals? Can Jenny speak French? 2、往往读升调； 3、译成汉语，都可以带上“吗”， 例如上面三句可分别译为：你父亲是老师吗？ 凯瑟琳喜欢动物吗？詹妮会说法语吗？,2.如果没有be动词、助动词、情态动词， 则根据动词的形式借助do的相应形式放在句首。具体方法是： a、如果谓语动词是原形，则借do； 例：They go to school by bike. Do they go to school by bike? b、如果谓语动词是一般现在时第三人称单数形式，则借does； 例：Bill gets up at 6:30 every day.Does bill get up at 6:30 every day? c、如果谓语动词是过去式，则借did. 需要注意的是，借does或did后，原句的谓语动词要变回原形。 例：The students saw a film yesterday. Did the students see a film yesterday?,（三）、陈述句变一般疑问句应注意的事项 陈述句变成一般疑问句除了遵循上述规则以外，还应注意下列几点： 1.如果陈述句中有第一人称，则变问句时最好 要变为第二人称。 I usually have lunch at school. Do you usually have lunch at school? My father is playing soccer. Is your father playing soccer? 2.如果句中有some, 则变问句时往往要变成any 。 There is some water on the playground. Is there any water on the playground?,3.复合句变一般疑问句通常只变主句，从句不变。 例：I know he comes from Canada. Do you know he comes from Canada? 4如果句中含有实义动词have且表示“有”时,除借do外，也可将其直接提到句首。 例：I have some friends in America. Do you have any friends in America? /Have you any friends in America?,（四）、一般疑问句的回答 一般疑问句往往采用简短回答，共由三部分（三个单词）组成，对这三部分（三个单词）的确定可以概括例下： 1.第一个词：不是Yes就是No。（注意：有时根据语气的不同，Yes可由Sure, Certainly, Of course等代替.No可由sorry 代替.） 2.第二个词：问谁答谁。即答语中的主语须与问句的主语一致（但必须用主格代词）。例：Does she clean her room every day? Yes, she does. Is Annas father a doctor? No，he isnt. 如果主语是 this that,回答时用 it 代替，如果问句中主语是these, those回答时用 they代替。,3.第三个词：用什么问，用什么答。即沿用问句中的引导词,例： Can Jim play soccer? Yes, he can. Does Mr Bean speak English? Yes, he does. 需要注意问题： 用 may 引导的问句，肯定回答用may，否定回答用 cant 或mustnt，用 must 引导的问句，肯定回答用 must，否定回答用neednt. 例： May I go to the park now? Yes, you may. /No, you mustnt. Must I wash my clothes now? Yes, you must. /No, you neednt. 4用No开头作否定回答时,结尾要加上 not。因为回答必须是三部分，所以否定回答必须缩写，而肯定回答不能缩写。例: Did Thomas come here yesterday? Yes, he did./ No ,he didnt.,三、特殊疑问句 （一）以疑问词开头，对句中某一成分提问的句子叫特殊疑问句。 （二）常用的疑问词有：,（三）小学阶段特殊疑问句句型结构有：1、特殊疑问词+助动词+主语+动词原形+其他？ eg: Where do you do study English? 2、特殊疑问词+be动词+主语+其他？ eg: Why is your Mum so angry? 3、特殊疑问词+情态动词+主语+动词原形+其他？ eg:What can I do for you?,（四）肯定句、否定句、一般疑问句和特殊 疑问句的相互转换,有am, is, are的句子: 1、肯定句变否定句：在am, is, are后面加上not,其余按顺 序照抄。 2、肯定句变一般疑问句：把am, is, are提前放到句首并 大写Am, Is, Are,其余照抄。 3、肯定句变特殊疑问句（就划线部分提问）： 第一步：先变一般疑问句 第二步：找合适的特殊疑问词代替划线部分 第三步：特殊疑问词提前放到句首，并大写，其余按 顺序照抄，省略划线部分。,例如：肯定句、否定句和一般疑问句的互换 肯定句：This is a book. 否定句：This is not a book. 一般疑问句：Is this a book? 肯定回答：Yes, it is. 否定回答：No, it isnt. 就划线部分提问(变特殊疑问句) This is a book. 第一步：变一般疑问句 Is this a book? 第二步：找合适的特殊疑问词 Is this what ? 第三步：特殊疑问词提前放到句首，并大写， 其余按顺序照抄，省略划线部分。What is this?,没有am, is, are的句子 1、肯定句变否定句：在主语后面加上do not或者does not, 其余按顺序照抄动词用原形 2、肯定句变一般疑问句：在句首加do或者does并大写, 其余照抄。注意：动词用原形 3、肯定句变特殊疑问句（就划线部分提问）：分3步骤 第一步：先变一般疑问句 第二步：找合适的特殊疑问词代替划线部分 第三步：特殊疑问词提前放到句首，并大写，其余按 顺序照抄，省略划线部分。 4.划线部分不能在特殊疑问句中出现。非三单时用do, 三单时用does,例：非三单 . 三单 肯定句：I like English 肯定句：He likes English. 一般疑问句：Do you like English? 一般疑问句：Does he like English? 否定句：I do not like English. 否定句：He does not like English.,就划线部分提问：I like English. 第一步：先变一般疑问句 Do you like English? 第二步：找合适的特殊疑问词代替划线部分 Do you like what? 第三步：特殊疑问词提前放到句首，并大写 ，其余按顺序照抄，省略划线部分。 What do you like?,特殊： 1.some变为any。 如：There are some birds in the tree.
